23 Claims.

highly skilled labor in operation. Another object is to provide agreasing and luring machine which is capable of efficiently andautomatically applying a greasing and luring compound to- .a hat withoutproducing streaks or spots thereon. Another object is to provide agreasing and luring machine capable of meeting high productionrequisites and at the same time reducing hat spoilage to a minimum.Another object is to provide a machine of the above nature capable ofeffecting uniform application of grease or oil to the hat at asubstantially constant temperature. Another object is to provide amethod of greasing and luring a hat which is not predicated on theexperience of highly skilled labor. Another object is to provide amethod of the above nature whereby a series of hats is uniformly greasedand lured, each hat receiving a uniform amount of grease or oil withoutthe production of streaks and spots thereon. Other objects will be inpart apparent and in part pointed out hereinafter.

The invention accordingly consists in the features of construction,combinations of elements, arrangements of parts and in the several stepsand relation and order of each of the same too-ne or more of the others,all as will be illustratively described herein, and the scope of theapplication of which will be indicated in the following claims.

In the drawings, which show several possible embodiments of myinvention,

Figure 1 is a sideelevation of my machine;

Figure 2 is a fragmentary elevation of the greasing pad and greaseapplicators of my machine;

Figure 3 is a fragmentary side elevation, partly in section, of theapparatus shown in Figure 2,;

Figure 4 is a fragmentary elevation of a modified form of my machine;

Figure 5 is a fragmentary elevation, partly in section, of another and,

Figure 6 is a fragmentary sidev elevation ,of the apparatus shown inFigure 5.

Similar reference characters refer to similar parts throughout thevarious views of'the drawparatus, and by conventionalmethods, the hat ismounted. on a hat block, and as the block is modification of my machine;

manipulated by the workman, he rubs the hat with hot grease, usually bya heated pad covered with a strip of cloth which acts as a vehicle forthe grease. The Workman heats the pad by first passing it over a hotiron. Practically all greasing is manually effected by highly skilledWorkmen of long experience, because a high degree of skill is almostprerequisite for satisfactory greasing. The grease must be hot whenapplied to the hat, and yet not so hot that its viscosity is such thatit can fall in drops from the luring pad and spot the hat. If the greaseis not hot enough it streaks the hat when manually applied, regardlessof the skill of the Workman. Carelessness or lack of skill also causesstreaks on the hat as the pad cannot abruptly be applied to the hatwithout creating streaks or spots. The pad must be applied with gradualpressure and with a sweeping ,motion vbecauseof the dryness andabsorptive capacity of the dry hat. Obviously this is a diflicult manualoperation.

There is considerable difiiculty in maintaining the greasing. padagainst the hat with a uniform pressure, because of the oval contour ofthe hat. As the greater diameter of the hat passes the greasing pad, thepressure of the pad against the hat tends to increase. If the workmandoes not relieve the pressure, excessive grease is applied. Thevreverseof this condition results when the lesser diameters of the hat pass thepad. Unless great care is taken to compensate for these conditions, ablotchy hat results which is useless as a finished product.

Hand greasing, by its nature, is carried on at non-uniform temperaturesand pressures, as the pad must necessarily be periodically removed fromthe hat to be reheated or replenished with grease. This periodicregreasing and reheating of the pad results in non-uniform greaseapplication causing streakiness. Furthermore, after the pad has beenapplied to the hat it is difiicult, if not impossible, to manipulate thepad in a manner to rub the grease into the hat, rubbing being one of thebest Ways-to thoroughly grease the hat without streaking or spotting it.

After the hat has been sufficiently greased it must be lured. Theconventional luring methods contemplate manual stroking of the hat inone direction with a dry hot cloth to lay the-nap of the hat in onedirection. This method, as well as the apparatus employed in itspractice is sub ject to the same objections as noted with respect to thegreasing operation, 1. e. considerable manual skill is prerequisite,high production is impossible, and imperfect luring is the rule, ratherthan the exception, because of temperature and pressure variations andthe fallibility of manual labor as compared with automatic machinery.

Accordingly, it is another object of this invention to provide agreasing and luring machine and a method of greasing and luring whichovercomes the above diificulties in a thoroughly practical and efiicientmanner.

Referring now to Figure 1, my machine in general comprises a head,column and base generally indicated at H), II and I2, respectively. HeadIt] forms a bearing for a spindle, one end of which carries a hat block13, and the other end of which carries a pulley l4 which is driven by abelt l5 trained around a pulley I6 which comprises a portion of a clutchl'l. Clutch 1! has a driving connection with a motor l8 which alsodrives a pulley l9 connected by a belt 20 to a lower pulley 2|. Pulley2| 'is provided to drive an oil pump (not shown) suitably mounted withincolumn ll. Thus motor I8 rotates hat block l3 through its operativeconnection thereto by clutch l'l, pulley l6, belt I5, pulley l4 and thespindle in head In. Reference to my Patent No. 2,137,250 issued November22, 1938, will afford a more complete description of the details ofconstruction and operation of these various parts.

Base II has secured preferably to the side thereof a hydraulic cylinderand piston generally indicated at 22. A piston rod 23 extends fromwithin the cylinder through a gland 24, and has secured to its outer enda rack 25 as by a coupling generally indicated at 26. Coupling 26 alsoprovides a mount 21 for a traverse control cam generally indicated at28, the specific natur and operation of which will be gone into ingreater detail hereinbelow.

A heavy bracket 29 (Figure 1) is suitably bolted to base 12 andcomprises a mount which pivotally supports a tool assembly generallyindicated at 30. For specific details of the structure by which thepivotal relation between tool assembly 30 and bracket 29 is effected,reference is made to my Patent No. 2,105,130 issued January 11, 1938.Rack 25 is connected by suitable gearing (not shown) to too] assembly 30so that upon reciprocation of the rack, tool assembly 30 is pivotedabout its axis to traverse the crown of a hat 3! mounted on block l3 ina path generally extending between the tip and brim of the hat.

A tool head generally indicated at 32 (Figure 1) is similar in nature tothe tool head disclosed in my Patent No. 2,137,250 referred to above,and accordingly includes a bearing portion 33 whereby the tool head isfreely swivelabl in relation to the lower portion of tool assembly 30.Thus the tool head traverses the crown of hat 3| and is also freelyswivelable in relation thereto. Tool head 32 includes a greasing andluring pad 34, about which, as is better shown in Figure 3, a strip 35of cloth is held. Preferably cloth 35 is fed from a suitable roll notshown) over the face of a relatively soft pressure pad 36 and over aguide roll 31 to mechanism (not shown) which is housed in a small casing38. In so far as the mechanism for feeding cloth 35 over the pad 34 isconcerned, such mechanism is substantially similar to that shown in myPatent No. 2,137,250. Thus, upon traversal of pad 34 over the crown ofhat 3i cloth 35 is periodically fed over the pad as described in myaforesaid patent.

During the traversal of pad 34 (Figure 1) rapid rectilinearreciprocation is imparted to the pad by mechanism housed within toolassembly 30 and driven by a motor 39 mounted thereon. The specificnature of the pad driving mechanism is disclosed in my Patent No.2,137,250.

As has been noted hereinbefore, it is desirable during the greasing ofthe hat that th pad be moving transversely to its direction of approachtoward the hat at the moment it touches the rotating hat to avoidspotting or'streaking the hat. Furthermore, it is desirable that thepressure with which the pad bears against the hat be maintained at asubstantially uniform rate as the pad traverses the hat. Theabove-described mechanism is well adapted to this end by reason of thereciprocatory movement of the pad, and by reason of the tension andtension relief springs (not shown) which force pad 34 against the hatwith an adjustable uniform pressure. These springs are controlled byknobs 40 and 4!, and the structure and operation of the springs and theknobs is specifically described in my abovenoted Patent No. 2,137,250.Also where oval hats are being greased I prefer to use an oval headassembly, e. g., such as is shown and described in my United StatesPatent No. 2,105,130, to neutralize the eccentric effect of the variousdiameters of a rotating oval hat.

My above-noted patents also specifically describe the hydraulicmechanism and control therefor briefly alluded to hereinabove, and accordingly this mechanism will be but briefly touched on herein.

As before noted, column I 1 houses an oil pump, and this pump issuitably connected to a sump in base l2 and to control valves (notshown) which are housed within a cover 42. One of these valves is areversing valve which has a stem, the upper portion of which is shown at43, stem 43 being connected as described in my above-noted patents to astarting lever 44. While the reversing valve is capable of automaticactuation, I also provide a manually operable reversing lever 45suitably connected to a bell crank 45 and capable of engaging a latch 41to accomplish manual operation of the reversing valve to effect reversalof fluid flow to cylinder 22. Automatic actuation of reversal valve isaccomplished by a bell crank generally indicated at 48, on arm 48a ofwhich is connected to a rod 49, the upper end of which may engage latch41 for the purpose described. Another arm 48b of hell crank 48 isengageable by travers control cam 28 and it is this engagement whicheffects automatic operation of the reversing valve. Thus, when lever 44is pivoted to the right, as shown in Figure 1, valve stem 43 isdepressed so that the reversing valve permits flow of fluid to cylinder22 in a manner to force piston rod 23 and accordingly rack 25 to theright. This eifects traversal of tool assembly 30 and accordingly pad 34about the hat crown from brim to tip thereof.

Inasmuch as the contour of the crown of hat 3| is not perfectlycircular, provision is made for moving tool assembly 30 and accordinglypad 34 radially with respect to the hat. To this end the tool assemblyis pivotally mounted on a heavy stud 50 and accordingly the assembly andpad may swing toward and away from the hat under the bias of thesprings, referred to above,-controlled by knobs 40 and 4|. My aforesaidpatents describe this structure in detail. The swinging movement of thetool assembly and pad, however, should preferably be guided andtherefore I provide a cam 5| of suitable contour which coacts with aroller (not shown) fixed to the lower portion of tool assembly 30. Asthis roller rolls over the upper surface of cam 5|, the position of pad34 with respect tothe crown of hat 3i is controlled so that the padengages the hat only in the places and at the periods desired. In myaforesaid patents the cams analogous to cam 5| are so contoured that thetool does not engage. the hat until ithas; been traversedsub stantia-llyto the tip thereof, "thereafter being in engagementwith the hat as ittraverses the hat from the tip to the brim, and thence back to the tip.,In greasing and luring certain types of hats, however; it is preferablethat the pad-first engage the brim portion" of the hat so that" in theevent spotting or streaking occurs when the luring pad first engages thehat, such'discoloration of the hat will occur-only at that portionsubsequently covered by the band. Accordingly, cam is contoured withthis in mind, and as it is undesirable in many instances for the pad totraverse the hat through 180, the traverse control cam 28"is so formedas to limittraverse of the tool assembly 30 and pad 34 to 90 startingfrom the brim or band portion of the hat. This is readily accomplishedby an adjustment of cam 28 afforded by a threaded portion 28a thereofwhich is adjustable through cam mount 21.

However, where initial greasing of the hat at the 'tip thereof isunobjectionable, cam 28 may be set up to .control traversal of theluring pad in substantially the manner described in. my aforesaidpatents. In such a case, pad 34 moves at a substantially rapid rate ofspeed from a retracted position opposite the band portion of the hat"toward the tip thereof, then engages the hat and" traverses it from tipto brim and back again at operative-speed and thence isdisengaged fromthe hat and returned it to its original retracted position at arelatively rapid rate, the variation in feed rate of the luring padbeing effected automatically bythe contour of the upper face of cam 28acting throughbell crank 48 to actuate a metering valve housed undercover 42,

a portion of this valve being shown at 52.

" In conventional greasing operations, the grease, or'oil is manuallyapplied to the hat'by a heated pad which has previously been coatedwithoil o rrubbed over a cake-of grease. Under these conditions it"isclear that under even the most favorable conditions the amount of greaseor oil on the pad is variable, and the temperature at which the greaseis appliedto the hat cannot be uniform, as -the pad mustperiodically bereplenis'hed with grease or-oil and heat. These conditions ofnon-uniform grease application and temperature'of Y application not onlylimit production, but 'also preclude the use of relatively unskilledlabor and result in substantial hat spoilage. To the preclusion of thesedifliculties the structure to be now described is directed.

' i As shownin Figure 1, tool head 3| has secured thereto a pair ofbrackets 53 and 54 which re-1 spectively carry" an oil or grease pipe55' and an air pipe 56. As shown in Figure 3, oil piper55 communicateswith anatomizer head or fitting 5'! which carries an atomizer 58 and aneedle valve 59. Oil pipe 55 is connected to an upper oil pipe 60 by afitting 61, the upper oil pipe being me as? 3| similarly to the spacingof jet'fi therefr'om.

If desired, upper air'pipe'63 may be provided v with a shut off valve66.

Asshown in Figure 1, air pipe 56 is connected by afiexible tubing 68 toa pipe 69 which, in turn,

' is connected in any suitable manner to a source of compressed air (notshown). Between flexible tubing .68 and the source of compressed air, 'I

provide a heater (not shown) of any suitable;

type, which heats the compressed airflflowing throughthe air pipesdescribed. Oil pipe 55 is connectedby a'fiexible tube 10 to a pipe llconnected" to ashut ofi valve 12 secured to the column ofthe machine. Apipe 13 leading from.

the band portion of'the hat, and jet 6,2"blows atomized grease againstthe hat immediately in front of pad 34 as the padtraverses the hatduring the greasi'ng'thereof. The amount of atom ized grease is easilyand accurately controlled by adjustment of the needle valves inatomizers 51 and 6| and it willbe apparent that .atomizing pressure andair temperature may also easily be controlled. Thus greasing may beeffected by unskilled labor under predetermined conditions oftemperature, atomization and pad pressure, and grease application, thusassuring uniform high production greasing and: minimum spoilage. Byreason ofthe .rapid rectilinear reciprocation of pad 34, the luringcompound is rubbed into the hat rather than 'spreadjthereon asbyco'nventional methods, and the'hat'surface is thus further improved. II

It isdesirabl'e that feed of grease start shortly before the pad isapplied to the hat, and stop at the reversal of traverse of the pad. Tothis end valve 12 referred to above is provided: Valve (2 may be aconventional type of automatic valve having a spring impelled plunger(not shown) connected to a stem'74 extending from the bottom of thevalve. A collar 75 on the upper end of reversal valve stem 43 suitablyengages one end of a lever 16 pivotedat T! to colconnected'to a secondatomizer generally indicated at 6|, substantially similar to'that justdescribed; Air pipe 56 parallels oil pipe to fitting 51 at which point ajet62 is taken off, atomizer 58 being disposed inthis jet. As shown inFigure -2, jet 62 extends'toward the crown of hat 3| at the left-handside of pad 34, the end of the jet being slightly spaced from thehatcrown. (see Figure 3) adjacent the pointat which the crown is engaged bypad 34. An'upper air pipe 63 is connected to lower air'pipe 56 by afitting 64- and extends upwardly of pad 34 preferably substantiallycentrally thereof, and terminates in an upper 'jet 65, the end. of whichis spaced from hat umn I I of the machine. Lever i6'ha's a free end 18which is positioned under valve stem' 14 of I valve'12 so that operationof lever 16 affects-the operative condition of valv 12. Thus, whenstarting lever 44 is swung'to the right, as viewed in Figure 1,- tostart the machine, counterclock wise motion of lever 16 results, causingupward movement of valve stem 14 toefiect communication" between greasepipes 13 and, H. This/permits the flowof grease. or oil under pressuretoatomizers 51 and 5|." When the operationcycle is over, reversing valvestem 43 is released by latch 4'! upon engagement thereof by rod .49 toeffect clockwise movement of lever 16. This permits stem '14 to drop,closing valve-12 to reak the connection between oil pipes 13 and It.

Thus, when the machine is not operating, grease such as provided on menshats, I have provided a modified form of apparatus as shown in Figures 5and 6. In this form I utilize a pneumatic hat support generallyindicated at 19 which includes generally a stationary hood 88' providedwith a slot 8! and Within which a hat block 82 rotates. This type of hatsupport is shown and described in detail in my copending application,Serial No. 226,442, filed August 24, 1938.

As shown in Figure 5, pad 34 is arranged to traverse'hat support 19along a path which follows slot 8|. Preferably pad 34 first engages thehat during the greasing operation :at the tip thereof and operatestoward the brim. The grease or oil is applied to the hat by a pair ofjets 83 and 84 connected by a pipe 85, both jets being connected toafitting 86 which is in turn connected to an oil or grease pipe 87.Fitting 85 includes a needle valve 88 which is operable to control theamount of oil passing through the fitting into a channel 89 formedtherein, channel 89 being in communication with jets 83 and 84. I

Channel 89 is also connected as by a pipe 90 to a T 9| connected to anair pipe 92. As is better shown in Figure 6, a lower air jet 93 isconnected to a T 9|, and an upper pipe 94 also connected to a T 9!terminates in an upper air jet 95. Air jets B3 and 95 are supported inany suitable manner adjacent the left-hand side of pad 34 as viewed inFigure 5 as, for example, by a strut 96 or the like, see also Figure 6.A somewhat similar strut 91 (Figure 5) is utilized to support jets 83and 84.

Oil pipe 81 and air pipe 92 are respectively connected to sources of oiland air under pressure, substantially as described with respectto oiland air pipes 55 and 56 (Figure l) In operation, heated air undersuitable pressure flows through pipe 92, through jets 93 and 95, andinto fitting 86 byway of pipe 90 and fitting channel 89. As the heatedair flows through the fitting, it picks up the grease or oil which flowspast needle valve 88 and forces it in finely dispersed form through jets83 and 84 against the hat body in advance of the pad 34 with respect toits direction of traverse over the hat. As the grease is applied to thehat, it is rubbed into the surface thereof by pad 34, as beforedescribed.

The apparatus shown in Figures 1, 2, 3, 5 and 6 is as useful for luringthe hat as it is for greasing the hat. Thus, after the hat has beengreased as described, clean, dry cloth may be fed over the pad, thereciprocation of the pad stopped, the feed of grease or oil shut off andthe pad, stationary with respect to its reciprocal action, traversedover the rotating hat. As the hot air is still being blown against thehat at uniform temperature, and as the pad bears against the hat at aconstant pressure while traversing it, the hat is rapidly andefficiently lured under circumstances impossible to approximate in themanual methods referred to.

Under certain circumstances it may be undee sirable to atomize grease oroil and blow it against the surface of the hat. Under suchcircumstances, I provide the apparatus shown in Figure 4, wherein pad 34carries a cloth strip 98 which is impregnated with grease or othersuitable compound. Impregnated cloth 98 is fed over pad 34 duringoperation of the pad as noted above with respect to cloth 35. In thismodification, the hat is heated by a pair of air jets 89 and I00connected in any suitable manner to a source of heated air. Jet I00 isstationary and is located adjacent the brim of the hat so as to directhot air toward the band portion only thereof; Jet 99 on the other handtraverses the crown of hat 3I with pad 34 and thus heats the hat as theimpregnated cloth 98 is rubbed thereagainst. Preferably jet ,99 isarranged at the rear ofpad 34 substantially centrally thereof and curvesover the top of the pad so that the outlet end of the jet directs theheated air against the hat crown in advance of the engagement thereof bypad 34.

It will now appear that I have provided a method of and apparatus forgreasing and luring a hat which attains the various objects referred toin a thoroughly eflicient and practical manner.

As many possible embodiments may be made of the mechanical features ofthe above invention and as the art herein described might be varied invarious parts, all without departing from the scope of the invention, itis to be understood that all matter hereinbefore set forth, or shown inthe accompanying drawings is to be interpreted as illustrative and notin a limiting sense.
